Ultra-Fine Perfection: 400, 1000, 2000, and 3000 Grit Sanding Sequence

When chasing a flawless, professional-grade finish, the 400 → 1000 → 2000 → 3000 grit sequence is a proven method. It’s ideal for automotive detailing, guitar finishing, and restoring high-gloss furniture.

Why This Sequence Works

400 grit levels the surface and removes imperfections. 1000 grit refines and smooths the workpiece, 2000 grit eliminates fine haze, and 3000 grit perfects the finish for an effortless polish.

• Wet/dry sandpaper in 400, 1000, 2000, and 3000 grit
• Spray bottle with water + drop of dish soap
• Microfiber towels

Step-by-Step Sanding Process

1. Initial sanding. Begin with 400 grit to remove imperfections and level the surface.
2. Intermediate smoothing. Move to 1000 grit for a refined texture.
3. Fine sanding. Use 2000 grit to remove micro-scratches.
4. Final sanding. Lightly finish with 3000 grit before polishing.
5. Polish. Apply a fine compound and buff to a mirror gloss.

Special Cases

On heat-sensitive materials like acrylic, keep the surface wet and use light pressure to prevent heat buildup.
